An improved machine tool includes a one piece, as cast base having a spindle drive motor mounting section, a wayblock mounting section, a tailstock mounting section and a tank for receiving coolant. The wayblock mounting section includes a basin having a rim and a plurality of upwardly extending projections in a central portion of the basin. Downwardly extending projections on a substantially as cast wayblock extend into the basin. A body of cast in situ material is disposed in the space between as cast surface areas on the upwardly extending base projections and as cast surface areas on the downwardly extending wayblock projections to hold the wayblock against movement relative to the base. A one piece as cast headstock has downwardly extending projections which are received in recesses formed in the wayblock. A second cast in situ body of material is disposed between surfaces on the headstock and the wayblock to hold the headstock against movement relative to the wayblock. An as cast tailstock support bar extends across a portion of the base which forms a coolant tank. Cast in situ bodies of material are formed between projections from the tailstock support bar and side surfaces of recesses in the base to hold the tailstock support bar against movement relative to the base. A chip conveyor assembly extends across the coolant tank to a location adjacent the headstock.
